LCD monitor and the combined integrated machine of individual video video recording digital TV set-top boxTechnical field
The utility model relates to and monitoring with LCD monitor and expansion field thereof, particularly a kind of all-in-one that LCD monitor and individual video video recording digital TV set-top box (PVR set-top box) are made up.
Background technology
Use the LCD monitor development of technologies along with monitoring, technology LCD monitor product has widely entered market in large quantities, since LCD monitor have easy to use, definition is high, the advantage in multiple input video source, LCD monitor is by the consumer acceptance.In technology longitudinal development, the horizontal integration of technology also is the certainty of LCD monitor production development.
From technical standpoint, present LCD monitor product itself has video. the audio frequency input, the VGA input, the S-VIDEO input interface, but can not use as television receiver, and can not record a video and playback to TV programme, therefore can not reach the multiple Presentation Function that a LCD monitor can realize corresponding various video source.
Summary of the invention
Deficiency in view of existing monitor technology, in order to improve the function of monitor, the spy provides a kind of diversification, compatibility LCD monitor and the combined integrated machine of individual video video recording digital TV set-top box (PVR set-top box) widely, thereby make a LCD monitor can realize the multiple Presentation Function in corresponding various video source, also can be used as television set and video tape recorder simultaneously and use.
The technical scheme that the utility model is taked for achieving the above object is: a kind of LCD monitor and the combined integrated machine of individual video video recording digital TV set-top box, comprise the TV processor in casing, the LCD monitor electronic circuit, video/audio decoder in the individual video video recording digital TV set-top box electronic circuit is characterized in that: the video/audio decoder in the described individual video video recording digital TV set-top box electronic circuit is connected with TV processor in the described LCD monitor electronic circuit respectively; The electronic circuit of described LCD monitor and individual video video recording digital TV set-top box places in the same casing.
Utility model has following beneficial effect, a LCD monitor has various video source receiving port, can show the various video signal, simultaneously, can compatible tv and the function of individual video video recording digital TV set-top box (PVR set-top box), received television signal uses as television set, can also record a video and playback, therefore has characteristics such as easy to use, compatible extensive.
Description of drawings
To be that the utility model is inner connect block diagram and as Figure of abstract to Fig. 1.
Embodiment:
Below in conjunction with accompanying drawing the utility model is elaborated:
As shown in Figure 1, the utility model comprises two parts, set-top box part: be through the tuner receiving digital television signal, deliver to demultiplexing module after the demodulation, obtain the digital television program A/V data in user-selected behind the demultiplexing, under the situation of normally watching program, the A/V data that obtain behind the demultiplexing are transported to audio/video decoder and hard disk simultaneously, decode respectively and broadcast and the time shift storage.When operations such as the user suspends, retreats, puts slowly, shifting state when set-top box enters, the passage that is transported to audio/video decoder from demultiplexing module is to cut-out, and decoder obtains the output of decoding of A/V data from hard disk, and the passage that demultiplexing module is transported to hard disk still keeps operate as normal.Tuner, the demultiplexing module of set-top box part, hard disk and audio/video decoder etc. are realized control by master controller by bus.
Monitor part: by the audio/video signal of the output of the decoder in the set-top box electronic circuit, deliver to the input of monitor TV processor, through the vision signal of TV processor processing is carried out mould/number conversion, noise reduction and scalar processing to signal by video frequency processing chip together with the VGA signal after, the LVDS signal is transferred on the LCDs the most at last, finishes Presentation Function.To behind the audio frequency amplifier, finally export to loud speaker by the audio signal output after the TV processor processing.
